74LVC2G240GN,115

Overview

The Nexperia 74LVC2G240GN,115 is a dual inverting buffer and line driver featuring three-state outputs controlled by active-low enable inputs (1OE, 2OE). It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5 V, enabling direct interfacing with 3.3 V or 5 V logic devices. The component utilizes Schmitt trigger inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It is housed in an 8-terminal XSON package (SOT1116) with dimensions of 1.2 x 1.0 x 0.35 mm.

Feature Summary

• Dual inverting buffers with independent three-state output control via active-low enable pins
• IOFF circuitry disables outputs to prevent damaging backflow current when the device is powered down
• Schmitt trigger action at all inputs provides high tolerance for slow input rise and fall times

Applications

• Mixed 3.3 V and 5 V logic environments requiring level translation
• Partial power-down applications utilizing IOFF functionality
• General-purpose buffering and line driving in portable electronics

Procurement Notes

Verify the specific ordering suffix ',115' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and marking code. Ensure that the selected variant matches the required SOT1116 package outline and temperature range specifications for the intended application environment.

Selection Notes

Select this component when a compact dual inverting buffer with three-state capability is required for mixed-voltage systems. The inclusion of IOFF circuitry makes it suitable for designs needing protection against backflow currents during power-down states. Verify that the operating voltage range and input threshold levels align with the source and load device specifications.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices manufactured by Nexperia. The 'GN' designation specifically identifies the extremely thin small outline package (XSON8) with no leads, corresponding to the SOT1116 outline. This series is designed for applications requiring wide supply voltage operation and robust performance in space-constrained designs.

Replacement Considerations

The datasheet lists other package variants of the same logical function, such as 74LVC2G240DP (TSSOP8), 74LVC2G240DC (VSSOP8), 74LVC2G240GT (XSON8), and 74LVC2G240GS (XSON8). These parts share identical electrical characteristics but differ in physical footprint and pinout orientation.
